Shaft Capacity Assessment of Recharge Impulse Technology

by Wafi Bouassida, Essaieb Hamdi, Mounir Bouassida, and Yuri Kharine

ABSTRACT: This paper discusses the performance of Recharge Impulse Technology (RIT) in increasing the shaft capacity of deep foundation systems regarding classical set-up processes. Based on the major contributors behind such performances: the shape effect and the electrical discharge installation, a case study is analyzed in view of highlighting that the coupling of these two components leads to a reasonable estimation of RIT shaft capacity with reference to in situ loading tests. A related design chart estimating the contribution of the shape effect in the increase of the shaft capacity had been drawn and a mean power law was proposed through a parametric study on the adhesion factor.
